Singer Vikki Carr demonstrates the forerunner of today's phonograph, the automatic musical instrument. She explains the hidden mechanisms whereby priceless pianos are played by the 'invisible hands' of pianist Ignace Jan Paderewski and composer - pianist Edvard Grieg, repeating precisely their performance of 50 years ago. These old orchestrations duplicate sounds of entire orchestras, played by player piano, automatic banjo, and other automatic instruments. Carr sings along with some of them in this fun and interesting film. Director Muriel Fox is a historically-important feminist and co-founder of the National Organization for Women (NOW).
